Amazon has launched its latest smart glasses, the Echo Frames, with a built-in Alexa voice assistant. This version, according to the manufacturer, retains a charge longer, has louder speakers and at the same time is lighter.

Frames can simply be connected to your phone and then say “Alexa” to talk to the assistant. It can answer you and will be heard even in a noisy room.

Amazon glasses can now play media files for up to six hours on a single charge. They also come in seven new styles. In addition to new frames, you can choose sunglasses and eyeglasses. All versions are waterproof and scratch-resistant.

The frames should also be noticeably less bulky than the previous generation of smart glasses. Amazon moved most of the internal wiring from the front of the glasses to the temples, resulting in a 15 percent thinner set of frames.

Echo Frames support connecting to two devices, so owners can more easily switch between multiple audio sources, such as a phone and laptop. There’s also a new notification filtering feature called VIP Filter, which prioritizes only the most “important” notifications.

Echo Frames owners will also have the ability to find a lost pair of glasses more easily thanks to Alexa by asking an assistant to “find my smart glasses.”

Recall that Meta, in partnership with the owner of Ray-Ban Luxottica, may soon release a pair of smart glasses. They will allow you to stream live videos on Facebook and Instagram and even hear the comments of people watching the broadcast.
